Question

4. (10 pts total) Use the typical vertical profile of ozone number concentration (molecules/cm³) to answer the following questions. z, km 40 25 10 012345 O3 profile piecewise linear approximation 03, 10¹2 molecules cm¹³3 a. (5 pts) Calculate the mixing ratio of O3 at sea level (z = 0 km, P = 101,300 Pa, T = 300 K) and 25 km (P = 3500 Pa, T = 220 K). Why does the difference in mixing ratios at 0 km and 25 km appear larger than the difference in number concentrations? b. (2 pts) The total number of O3 molecules in the atmosphere per unit area (for example, 1 cm²) is called the "O3 column concentration" and determines the efficiency with which the O3 layer prevents UV radiation from reaching the Earth's surface. Estimate the O3 column (i.e., molecules per cm²) in the above profile by approximating the profile with the "piecewise linear function" shown as the thin solid line (Hint: recall that the area of a triangle is 2*base*height). c. (3 pts) To illustrate how thin the stratospheric ozone layer actually is, imagine that all of the O3 in the atmospheric column you calculated in part (b) were brought to sea level as a
